Parallel Analysis not working #829
Description
Description
Parallel Analysis doesn't work. This seems to be due to two ghdl instances trying to write to the library file.
Expected behaviour
You should be able to Analyse in parallel for use with make -j

How to reproduce?
% cat a.vhdl
entity a is
end a;
architecture behav of a is
begin
end behav;
% cat b.vhdl
entity b is
end b;
architecture behav of b is
begin
end behav;
% # Normal serial build works

% cat work-obj93.cf

The second parallel build is missing the a.vhdl entry in work-obj93.cf
Also sometimes results in ghdl:error: cannot update library file "work-obj93.cf"
